T形头单向螺栓连接T形组件抗拉性能研究
Tensile Performance of T-Stub Components with T-Head One-Side Bolts
摘要
Abstract
The novel T-head one-side bolt can effectively solve the problem that the traditional high-strength bolt cannot be directly applied to the bolted beam to tubular column joints.However,the bearing mechanism of each component in the beam-column joint with this novel bolt is still unclear and needs to be further explored.The T-head one-side bolt is characterized by the shape of the bolt hole on the endplate and tubular column.To explore the mechanical response and bearing mechanism of the endplate and beam components in this novel bolted connection,the finite element analysis software ABAQUS was used to carry out a systematic numerical analysis on the tensile performance of the T-stub connections based on the component method.The main research contents and conclusions are as follows:an accurate three-dimensional finite element model of the connection was established,and five yield line patterns on the T-stub flange in T-head one-side bolted joint was studied.Finally,the calculation formula for the yield strength of T-stub joints with T-head one-side bolts is given based on the principle of virtual work and the yield line theory.关键词
